Abstract

To study the effects of different treatments on breaking SEED DORMANCY on Littleseed Canarygrass a factorial experiment based on RCBD with 4 replications was conducted at the Weeds Science Laboratory Ferdowsi University of Mashhad.19 treatments were selected for this experiment. Treatments include: Hot water treatment (500c for 2, 4 and 6 minutes), treated with sand paper for 5 minutes, concentrated sulfuric acid (3, 6 and 9 minutes), stratification at (5 and 10 0c) for 5 days, concentrated sulfuric acid for 3, 6 and 9 minutes+5 days of stratification, soaking treatments 24, 48, 72 and 96 hours, treatment with potassium nitrate , potassium nitrate+ stratification treatment and control were used for this experiment. The results showed that the effect of light conditions (light/dark and constant darkness) and the effect of different treatments on SEED DORMANCY and two light regimes on the littleseed Canary grass seed GERMINATION, but the study of treatments for the seeds to sleep Canarygrass was observed a significant difference at p<0.01 level. Results showed that had (96%) sulfuric acid 6 min at two levels of continuous darkness and light/dark had the greatest effect that respectively, were 93 and 98% percent. The lowest GERMINATION percentage was observed in control treatments and moist chilling for 10 days, respectively, 16.5 at light/dark condition and 11 percent at continuous darkness condition in breaking dormancy of littleseed canary grass seeds indicating that likely HARD SEED COAT in the primary mechanism of SEED DORMANCY in littleseed canary grass.
